This is an application selection scenario, not a claim about a named customer or a measured commercial result. Final values follow the agreed product specification and controlled trial.
Application background
A blasting operation may be cleaning a surface, removing an existing layer or creating a profile for coating adhesion. Brown fused alumina is a tough abrasive candidate, but the media grade alone does not determine the result. The substrate, nozzle, stand-off distance, pressure, feed rate and reuse cycle must be included in the selection record.
Common problems
- A coarse grade is ordered before the required surface profile and coating system are defined.
- Pressure is raised to compensate for poor media flow, changing dust and substrate impact at the same time.
- A reused abrasive is judged by its original grade label even after fines and contamination have accumulated.
Material requirements
Define the workpiece material, coating or cleanliness target, permitted substrate loss, target profile method and acceptable residual contamination. State whether the process is dry or wet and whether media will be reclaimed. Request the F designation, particle-size distribution, chemistry and any magnetic-content limit needed for the specific work.
How to select brown fused alumina
Compare more than one candidate grade under a fixed nozzle and pressure setting. F24, F36 and F60 can be discussion points across coarser to finer trials, but the final choice must be based on the measured surface outcome. Use a representative substrate panel; measure the resulting profile and cleanliness with the site's accepted method rather than relying on visual appearance alone.
Recommended grit or product family to evaluate
Start with the CHAOYAN F grit family. Request individual F24, F36 or F60 product data as candidates based on the current blast setup. Keep each grade's lot and reuse history separate so a field test can be reproduced.
Processing considerations
Check dry media storage, metering, nozzle wear and dust extraction. If media is reclaimed, monitor the retained fraction, fines, foreign debris and change in cutting action over successive cycles. Set a discard or refresh rule from measured process performance, not a fixed number of reuses copied from another site.
Expected technical effect to verify
The trial should show whether the chosen abrasive reaches the specified surface condition without unacceptable substrate damage or contamination. Media consumption, dust and profile consistency should be recorded as observed data. The page does not promise a percentage gain or a fixed number of reuse cycles.
Common mistakes
- Calling a micron reference an exact diameter for every F36 particle.
- Changing pressure, nozzle and abrasive at once during a comparison.
- Using the original grade label as the only control for reclaimed media.
